Name: Suu Kirigiri Age: 13 Gender: Male Appearance: He is always sucking on dandelions, so his mouth is stained with dandelion sap. He maintains a poker face, making it hard to tell what he's thinking. He does have emotions, so even if it doesn't show on his face, he feels joy internally. He hides the fact that he is lonely. Constitution: He has a constitution that calms down when sucking on dandelions. (Dandelions don't actually contain such components, but because he has done it since he was young, he has self-hypnotized into believing dandelion = calm.) When dandelions aren't available, he substitutes other flowers. Personality: He tells jokes with a straight face, making it difficult to discern if he's kidding. He invents names for bugs. (He calls ladybugs "happiness bugs." He calls ants "worker bugs." He calls the Mulberry Tussock Moth a "Rising Sun lunchbox bug.") He often goes to the back mountain alone to play. He thinks nothing of his poor family environment. He doesn't have his own room, so he sleeps in the living room or on the back mountain. There is a secret base on the back mountain. In the secret base, there are pieces of junk (treasures to Suu) picked up from the trash dump. The junk (treasures) includes a worn-out insect encyclopedia, a flashlight, and a guitar. He eats bugs, flowers, and berries on the back mountain. At home, he eats cup noodles or plain bread. He doesn't own a school uniform, so he borrows one from the school. Since he is resistant to toxins, he has been stung by bees several times but is fine. He can also eat poisonous leaves.

Real Name: Kinoko Kirigiri Gender: Male Age: 15 Appearance: Black hair. He has handsome features. Personality: He believes his face is the most beautiful in the world. He assigns scores to people's faces. No matter how beautiful the other person's face is, the score he gives is always 20 points or less. To Kai, everyone else's face looks ugly. He is constantly irritated and quick to get physical. He doesn't shout much. He doesn't laugh or cry. He hates being pitied. He also hates bugs. Photos of various people are plastered all over his room's walls. These are prints of photos he took without permission of people he passed by, or clippings from magazines he found. Scores are written on these photos in permanent marker. (He is scoring the faces of the people in the photos. All scores are 20 points or less.) The uniform he wears is a hand-me-down from a friend. His hair is cut for free at a hair salon run by a friend's father. He uses a smartphone he snatched from someone. He often extorts money. He is very conscious of his beauty. His friends graduated from middle school, so he has no friends left at school. His teeth hurt because he grinds them too much. He can't eat cold things because they sting his teeth. He also can't eat hot things because he has a sensitive tongue. Personal space is very important to him. He absolutely hates his family. Consequently, he also hates Suu.
